摘　　要：生物识别技术已广受重视,利用AES加密算法对生物识别过程中的特征模板进行加密可以大大提高生物识别技术的安全性。为提高AES加密算法的吞吐率,使其更好地应用于生物识别领域,以FPGA为实现主体,采用串行缓存结构,充分利用FPGA并行处理的特点,成功实现了一种大吞吐量的AES算法。最后在Xilinx的XC7A200T芯片上对算法进行了验证,经计算其理论吞吐量可以达到30.3 Gb/s。Biometrics is now more and more important to many occasions, encrypting the templates which generated in the process of biometrics using the AES encryption algorithm can enhance the safety of the biometrics significantly. In this paper, an AES encryption algorithm is proposed,which could improve the throughput rate of AES, and make it better in applications. Based on FPGA and parallel processing,a high throughput rate is achieved and verified on the XC7A200T chip. The results are performed and discussed.
